Thanks Leadsled! I was checking that link out and saw that there is an upcoming 4 day course on nutrition farming that is going to be given here in Ontario this fall by Graeme Sait and Joel Williams. Likely my only chance to catch this kind of talent, so going to sign up for this one.

Note that the only other North American course will be held in Portland Oregon. Details on the link provided above.

Graeme is excellent...great speaker. Enjoy...his tcec ratios are what I shoot for

YEa I saw those tour dates and am considering hitting up the Portland course. Anyone else doing the Nova Crop Control webinar tomorrow?

FE, I am considering the Portland dates as well.

 

[FatherEarth]

we should link up..

finally caught up to page 71, this is the best thread i can remember reading. thanks for everyone sharing. can anyone tell me the best way to get the liquid from the leaf for the refractometer?

Roll up a leaf and smash it with pliers.
or can get a sap press. Pike makes modified vice grips for squeezing out sap.

1 of my 3 replacement boxes arrived today. apparently the other two blew up in shipment again.

the seastim that came today looks like a football. I'm surprised it didn't explode as well. no bags around any of the jugs which seems odd considering their track record.

This one sounds interesting, although I dont care for the name..lol

FE...do you know anything about the crystalline structure of this? Is it plant available? Is it naturally occuring...under high heat?

 

[FatherEarth]

I haven't a clue. I was reading something totally unrelated and it mentioned calcium silicate and I thought 'hey'..! Maybe there is CaSi for plants!?... and that search led me to that link...

I read a little about Calcium Silicate a while back. If I recall there are two main sources. One is a by product of steel slag, the other is a mined source called Wollastonite.

There were some pretty interesting studies done by Joseph Heckman of Rutgers where they grew test plots with Calcium Carbonate and Calcium Silicate as the liming agents. The Silicate plots showed increased disease resistance and in some cases yield. Pretty interesting.

Not sure where to find the whole study but this newsletter has some info: https://njaes.rutgers.edu/pubs/soilprofile/sp-v20.pdf

 

[milkyjoe]

Yea...I am hunting wollastonite. The steel slag is probably processed at high enough temp to crystallize the sio2

so, would / could it be as simple as amending soil with crushed wollastonite?

 

[milkyjoe]

PH wise the silicate will behave pretty much identically to carbonate. So instead of amending with lime you can replace that with wollastonite. It is not a replacement for gypsum though as the sulfate acts differently.

 

[Avinash.miles]

apparently wollastonite is used in glazes on clay; comes pretty cheap in that form and is finely powdered....
is that a safe bet for adding to soil?

also; you must spread some reputation around before giving it to milky joe again

 

[TheSilverMullet]

It doesn't seem like companies are marketing the Wollastonite as a soil amendment unlike the slag based silicate. Not sure why.

Vansil brand Wollastonite is OMRI certified as of 2014 FWIW.
